Abstract
The utility model relates to a kind of filter strainer plate filter syndeton of not leakiness material, comprises filter, filter plate, rubber blanket and nut; The filter bar of filter is provided with screw thread, and on filter plate, equi-spaced apart arranges the screwed hole suitable with filter bar screw thread, and filter bar, directly by being screwed on the screwed hole of filter plate, the filter bar that filter plate bottom is exposed installs rubber blanket and fastening nuts.The utility model filter is installed firmly, and no longer loosening, short grained sandstone is not entering in water along filter opening; Even if nut occurs loosening phenomenon, the filter bar due to filter is connected with filter plate by screw thread, do not have the space that sandstone can be slipped away, so also there will not be sandstone to leak the problem of material along filter opening.The utility model is simple and feasible, effectively prevents filtering head of filter from loosening, and improves the filter effect of filter, extends the life cycle of filter, reduces the maintenance cost of filter.Control the running of filter preferably.
Description
Technical field
The utility model relates to sandrock filter filter plate and filter, particularly a kind of filter strainer plate filter syndeton of not leakiness material.
Background technology
Water treatment sandstone filter is that a kind of cobblestone, quartz sand and anthracite of adopting is as the filter plant of filter medium.Retain method except the impurity in anhydrating and greasy dirt, the turbidity of water in reduction system mainly through filtering, thus meet process water requirement.The impurity retained when filtering layer is too much, and the hole in filtering layer is blocked, and the resistance of current increases, and the rate of filtration diminishes, and filtering traffic will decline in a large number.For recovering the original rate of filtration of filter and flow, must carry out backwash by regular clear water, the greasy dirt in filtrate and impurity are washed out filtrate, thus recover the filter capacity of filtering tank filtrate, this backwash process is called backwash.At present, during sandrock filter backwash, because backwash current are comparatively large to filter strainer plate, filter and filtrate impulsive force, cause in backwash process and often occur that filter loosens, the bed of material is chaotic, run material phenomenon, cause filter material layer thinning, poor filtration effect.After filter loosens, short grained sandstone can enter along the installing hole installing filter in the water after filtration, and cause containing sand grains in effluent quality, water quality is poor, directly affects production, and the associated maintenance expense of filter also increases greatly.
Filter is the captation of sandrock filter, is arranged in the bottom of filtrate, is connected with filter plate.The mounting means of tradition filter is: the filter bar of filter is threaded, and filter bar directly inserts the circular mounting hole that filter plate bores, and is then connected with filter bar at filter plate bottom nut, directly tightens.Installing hole diameter due to filter plate is greater than the diameter of filter bar, when filter sand stone Filter Back Washing, the impulsive force of backwash current to filter strainer plate, filter is larger, filter is caused to loosen, short grained sandstone can enter in the water after filtration along the installing hole installing filter, cause containing sand grains in effluent quality, water quality is poor, directly affects product quality and production.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of filter strainer plate filter syndeton of not leakiness material, prevents filtering head of filter from loosening, and improves the filter effect of filter, extends the life cycle of filter, reduces the maintenance cost of filter.
For achieving the above object, the utility model realizes by the following technical solutions:
A filter strainer plate filter syndeton for leakiness material, does not comprise filter, filter plate, rubber blanket and nut; The filter bar of filter is provided with screw thread, and on filter plate, equi-spaced apart arranges the screwed hole suitable with filter bar screw thread, and filter bar, directly by being screwed on the screwed hole of filter plate, the filter bar that filter plate bottom is exposed installs rubber blanket and fastening nuts.
Described nut quantity is two.
Compared with prior art, the beneficial effects of the utility model are:
The utility model filter is installed firmly, and no longer loosening, short grained sandstone is not entering in water along filter opening; Even if nut occurs loosening phenomenon, the filter bar due to filter is connected with filter plate by screw thread, do not have the space that sandstone can be slipped away, so also there will not be sandstone to leak the problem of material along filter opening.The utility model is simple and feasible, effectively prevents filtering head of filter from loosening, and improves the filter effect of filter, extends the life cycle of filter, reduces the maintenance cost of filter.Control the running of filter preferably.
Accompanying drawing explanation
Fig. 1 is filter plate filter syndeton schematic diagram of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure: 1-filter 1.1-filters bar 2-filter plate 3-screwed hole 4-rubber blanket 5-nut
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1 and Figure 2, a kind of filter strainer plate filter syndeton of not leakiness material, comprises filter 1, filter plate 2, rubber blanket 4 and nut 5; The filter bar 1.1 of filter 1 is provided with screw thread, on filter plate 2, equi-spaced apart arranges the screwed hole 3 suitable with filter bar 1.1 screw thread, filter bar 1.1, directly by being screwed on the screwed hole 3 of filter plate 2, rubber blanket 4 is installed by the filter bar 1.1 that filter plate 2 bottom is exposed and two nuts 5 are fastening.
The problem of above-mentioned syndeton existing backwash leakage material under solving conventional mounting mode, improves the effect of filter.
Be only general principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
